PAINT-DISTRIBUTER.

SPECIFICATION forming part of Letters Patent No. 298,138, dated May6,1884.

Application filed September 10, 1883. (Model.)

To all whom, it may concern.-

Be it known that I, LIBERTY WALKUP, a citizen of the United States,residing in the city of Rockford, in the county of Winnebago and Stateof Illinois, have invented a new and useful Improvement inPaint-Distributers, of which the following is a specification.

This invention relates to machines employed in the distribution ofpigmentsin the art. of painting, but more especially in the fine arts.

The object of this invention is to produce a more efficient machine ofits class in a more convenient and practical form; and it consists inthe novel construction and arrangement of the parts, and in themechanism employed as embodied in the accompanying drawings, all ofwhich will be hereinafter more fully described.

In the accompanying drawings, Figure 1 is a plan view of a machineembodying my invention, and in which the operative parts are in theircentral position in the case. Fig. 2 is an under face view thereof. Fig.3 is a plan view with the cover removed, and in which the operativeparts are in their forward position. Fig. 4 is also a plan view with thecover removed, and in which the operative parts are Fig. 5 is a frontedge view. h Fig. 6 is a front end View, in which the vertical air-tubeand the pigmentreceptacle are shown in central section. Fig. 7 is avertical central section of the wind-wheel and walking-beam. Fig. '8 isan isometrical rephand-piece is composed of a bottom, A, and

vertical edges B, in this instance of plate material produced in the boxform represented, having its forward end portion, A, inclined rearward,and oblique or inclined to the horizontal plane of thehandle ,portion,having its rear edge, A on a higher plane. This forward inclined endportion is provided with a lid or cover, 0, made removable, or having ahinged connection with the upper edge of its 'cover.

rear vertical wall in a manner to permit it to open rearward to exposethe working parts located within the forward section of the case. Thishinged cover is provided toward its forward end with a crystal, a,through which the movement may be seen without opening the The handleportion of this case is provided with a cap, D, having a detachable orhinged connection with the vertical side walls thereof. The removal ofthis cap, in connection with the hinged cover when open, serves toexpose the working parts contained within the case.

At It is represented a wind-wheel support, of bed-plate form, on whichto support the main working parts of the machine. This bedplate isplaced in the forward end f.,tl1'e case, and is connected to the bottomthereof by means of screws 1), passed through oblique slots [2, formedin the bottom of the case, and screw-threaded into the bed-plate in sucha manner as to permit the plate to move endwise in the casein thedirection of the slotopenings.

At 7) is represented a springwasher, placed under the head of one of Ithe screws b, on the outer side of the bottom plate of the case, toregulate the friction of the bed-plate on the bottom thereof.

At F is represented a wind-wheel composedsuitable foot-bearing in thebod-plate and in an adjustable screw-bearing in the free end of theoverhanging arm 0, rising from the bedplate and overhanging the wheel onits upper .side.

At d is represented a vertical shaft,supp0rted to oscillate in afoot-bearing in the bedplate and in an adjustable screw-bearing in thefree end of the overhanging arm (1, rising from the bed-plate andoverhanging the upper end of the shaft.

' At 6 is represented a walking-beam fixed to the vertical shaft d, tooscillate-with the shaft. Both arms of this walkingbeam are slottedlengthwise, and its rear slotted arm extends IOO over the wind-wheel andreceives the wrist of the crankshaft 0 thereof. The forward slotted 'armof the walking-beam extends through a slot, c,formcd in the forwardvertical end wall thereof, and immediately outside of the case receivesthe wrist or downturned end of the needle h.

At h is represented a guard-plate fixed to the forward vertical end wallof the casein the plane of the lower wall of theslot c,from which itextends forward to protect the forward free end of the walkingbeamprojecting from the case over the plate. The vertical arm h of thisplate extends lengthwise of the vertical end wall, and its inner face isreduced to form a vertical slot, 1', between it and the verticalend-wall of the case. This vertical slot i secures the wrist or innerend of the downturned arm oftheneedlch, depending through the slottedfree arm of the walkingbeam, in such a manner as to permit a freereciprocating movement of the needle in the direction of its length. 7

At His represented a pigment receptaclein this instance of spoonformprovi(:led with an arm, 7:, extending rearward 011 the front edge ofthe case, having a pivotal connection therewith at 7.:'in amanner topermitits spoon portion to swing downward from the case. The rear edgeof the spoon portion is provided with a lip-extension, (represented indotted lines at 7n,) designed to engage an indentation in the edgeportion of the case, to hold the spoon in connection therewith in adetachable manner, and in position thereon to receive the needle in itsangle center.

At 1 is represented a finger, pivoted at one end to the vertical endwall of the case, and capable of a swinging movement in the verticalplane of theneedle, and having its free end forked to engage the needlewhen in its downtnrncd position, to hold it in the center of thereceptacle to give direction to its reciprocating movements.

At 1 is represented anair-tube, supported on the bed-plate in suchposition relatively with wind-wheel that a current of air forced throughits nozzle end will be delivered onto I the buckets of the wind-wheel tocause it to revolve. This air-tube is fitted withasinglewayeheclr-valve, 1,, to regulate the flow of air through the tubeto the wind-wheel. This valve is fitted with a lever-arm, Z, projectinglaterally from its upper end, having its free end portion extendingthrough suitable open- 1ng in the free end of an arm, Z', fixed to therear vertical wall of thecase in a manner to out points in theback-and-iorth movement of the bed-plate. This air-tube I is connectedwith a branch tube, m, by means of a flexible tube, K, in a manner notto interfere with the back-andforth movement of the bcd-plate.

At L is represented the main tube, a portion of which extends rearwardthrough the case, andis designed to connect with the air-supply. Thebranch tube in connects with this main tube within the case, andreceives the rear end of the flexible tube K.

At )1 is represented a branch of the main air-tube, which extendsforward in the case and outward through the front edge thereof near itsforward end, and its outer end is fitted with a vertical nozzle, at,opening centrally over the needle in front of the pigment-receptacle.The rear end portion, a, of the main tube, extending through the rearend of the case, is fitted in valve-seat form, as represented atn,consisting of a prominence projecting inward from one side of thetube, and an ex ternal opening on the opposite side thereof centrallyover the prominence. This projecting end portion of the main tube isprovided with a flexible tube, a, which extends over the external sideopening in such a manner that when pressed into the side opening of thetube it will engage the prominence projecting inward from its oppositeside, and close the passage and cut off the flow of airthrough the tube.The extreme outer end portion of the main air-tube L receives the endportion of a flexible tube, P, designed to connect with the air-su1')plv.

At It is represented avalve-lcver placed within the case, having apivotal connection at 0 with the bottom thereof. The rear end of thisvalve-lever extends outward through the rear end of the ease, and itsprojecting end,at o,is fitted to engage the flexible tube a over theside opening in the main air-tube L to press it against the prominencein the tube front side of the case, which is slotted to receive it in amanner to permit of a back-andforth movement of its free end in thelengthwise direction of the case. The inner end of this thumb-leverispivoted at p to the for-- ward end of the valve lever in such a mannerthat its inward endwise movement will counteract the force of thespring 1) and open the valve.

Att is represented a connecting-link, having a pivotal connection ofoneend, at t, with the bed-plate E. and a pivotal connection of itsother end, at t, with the thumb-leverT near the center of its length, bywhich the backward and forward movement of the free end of thethumb-lever will impart an endwise back-and-forth movement of thebed-plate and of the several parts mounted thereon.

At a is represented a thumb-screw, having a screw-thread connection withthe case at its forward. end, in such position that its inner end. willengage the bed-plate to limit its forward movement. By means of thisthumbscrew the forward movement of the bed-plate may be regulated tolimitit at any point within the limits of the devices.

At a is represented a rod fixed to the front edge of the case, andextending forward there-. of in position to be received in the left handof the operator, to enable him to control the movements of the machinewith greater certainty.

In the use of my improved paint-distributer, the main air-tube isconnected with the air-supply. The pigment, in liquid form of a properconsistency, 15 then placed in the receptacle H. The valve 0 is thenlifted from its seat by depressing the thumb-lever T, which permits aflow of air, under pressure, to pass through the branch pipe I- andimpinge upon the buckets of the wind-wheel, causing it to revolverapidly, and by reason of its crank and walking-beam connection willimpart a rapid endwise-reciprocating movement to the needle connectedwith the walking beam. In this movement the needle, through the pigmentcontained in the receptacle, will, in its outward throws, carry with ita quantity of the pigment under the air-jet delivered from the verticalnozzle it, which 5 jet of air will disengage the pigment from theprojecting end of the needle and deliver it in finely-divided particlesor spray to any surface a proper distance below the needle. The quantityof pigment delivered at each outward throw of the needle and thecharacter of work of which the machine is capable are dependent, mainly,upon the rapidity of the vibrations of the needle and the length of itsthrows. These, for the various kinds of work to which the machine isadapted, require that they be under the control of the operator, to beused at any point within the capacity of the devices. This I accomplishin my improved machine by means of the thumb-lever and its connectionwith the working parts, from which it wilhbe seen that with thethumblever in its rearward depressed position, as shown in Fig. 4, thecheck-valve t will be open to its greatest capacity to impart to thewheel its greatest velocity, and the relative-position of the wheel tothe needle will be such as to impart to the needle its greatest throwand give to the machine its greatest capacity for the distribution ofthe largest quantity of the pigment. Vhen the thumb-lever is in itsforward position, as shown in Fig. 3, if depressed to open the valveinthe main tube, the checkvalve i will be in position to deliver 7 thesmallest quantity of air to the wheel, to cause it to revolve at itslowest velocity; and the relative position of the wheel with the needlewill be such as to impart to the needle its shortest throw and reducethe capacity of the machine for the distribution of the pigment to itslowest point. Between these extremes the machine, by means of thethumb-lever, is under thecomplete control of the operator, to regulatethe distribution of the pigments as the'character of the work mayrequire in the judgment of the operator.
